in the bios that i am unfamiliar with but clearly are doing something with voltage set to auto. As it is 100% stable at auto, but not if i manually put it to the voltages it runs at
Everything is set to auto, other then the core multiplier,XMP, intel speed step technology (witch is disabled, so it doesn't change frequencies and stays at what i put it at.) and lastly LLC witch is set to lvl 3
also the 1070 in alot of more recent titles isn't even fully utilized with the i5 8600k set to 4.6ghz or even 4.9ghz, especially in MP games. It's pretty easy to become CPU bound with this processor in MP games. (it's only got 6 cores with no HT)
or are you going to just argue with me over if i should even be Overclocking it or not.
it's just not helpful, or productive to be having that conversation.
Degradation is a concern, and used systems already bring lower guarantees. Unless you're going to guarantee its stable operation while overclocked for months/years, I think you might be putting unwarranted effort into it. It's not going fetch a reasonable amount extra because it's got some extra hundreds of MHz.
This isn't saying "don't try" mind you. This is just saying you may have to consider stable operation above a slight extra bit of performance that honestly won't be noticeable unless you benchmark. Just answering with what I'd prioritize on if I was either buying or trying to sell a platform of that age.
As for the overclock, it sounds like it needs 1.4V for your desired clock speed. 600 MHz is nice, but are you comfortable selling a CPU of that age that....
1. Needs that much voltage.
2. Seems to be right on the edge as it fails just under it, and might not stay stable that way for long?
Maybe settle a couple hundred MHz lower. That would still be something above the stock 4.3 GHz. If this is an all core frequency you're attempting, I wonder if nearer to 5 GHz is too ambitious for it?
i've had this cpu since 2017, and i always had it clocked at 4.6ghz with 1.265v and nothing else changed (other then XMP) never crashed at that speed/voltage over the years
only recently within the last year or so have i been casually trying to
get it to 4.9ghz/5.0ghz so that when i did eventually upgrade i could sell it with it's best performance possible (i have now upgraded so i am actively trying alot more)
it is stable currently at 4.9ghz with auto Voltage and llc lvl 3 but as mentioned the Voltage is pretty damn high. since temps are fine i'm wondering if there are other settings to change
that would help me lower that voltage to something around 1.35v while remaining stable
as, as you mentioned i don't know how long the CPU will be stable at such a high voltage
5.0ghz may or may not be stable with the same settings (i haven't tried it other then booting windows with the same settings i have with 4.9ghz)
But the voltage goes into the 1.42/1.45v range witch is far far to high for me to be comfortable even running it at any extended time period
the most i did with it was put it through cpu-z validator
https://valid.x86.fr/3xdcr1
(for some reason the screenshot shows 1.344v even though i seen it
bounce between 1.425 and 1.455, probably a cpu-z bug)
Lastly yes this is a all core oc i am using.
the reason for this is because if you have anything else open
such as chrome or discord, it will use the AVX offset even when playing a game.
i had it set to 2 for a while when testing 4.9ghz and having ether of those programs just open in the background made the clock speed go down to 4.7ghz unless i closed them.
making the OC pointless.
i'd say the majority of people are going to have ether open while playing games
so AVX offset isn't something i'm interested in even applying.
If the settings you used to be able to run no longer work without crashes, then it's because the silicon became degraded as the settings were never actually safe for every day use.
If the settings never worked then it's more likely due to the CPU being a lower quality binned sample, if not just bad settings.
Loadline Calibration can easily screw you over if it's improperly set, too far one way or the other and it'll either undershoot or overshoot on voltage, overshooting with LLC can easily pose a risk of degradation (or even killing the CPU) by overshooting to absurd levels (i.e. 1.5v or higher), whereas undershooting will obviously just make the overclock settings unstable under load.
Generally, the middle settings are the best to work with for LLC; ASUS and MSI generally go with "Mode x" as the structure whereas Gigabyte uses things like "Normal," "High," "Extreme," etc.
If the range is between modes 1 through 8, for example, then mode 4 and 5 are the best to start with as they result in the least amount of overshooting and undershooting, and if you have to use a higher LLC for overshooting to gain stability, then I'd assume that there's just not enough core voltage and that it could be bumped up at least a step or two. You should really never use LLC to crank out more voltage, ever, it's better to gradually tweak vCore in small increments until the overclock is stable, and keep LLC at a middle setting where it remains rather consistent if you're going to use LLC at all.
That EVGA N1 series power supply is also concerning, because it's a very low quality series that I wouldn't really trust in an overclocked system due to it being less reliable. It's not even 80 PLUS certified.
Overclocking isn't going to raise the value, especially if you can't figure it out on your own and don't even know what binning is, if anything you're going to devalue it by damaging the hardware by doing it improperly. Not all 8600Ks can reach 5 GHz, and only 87% of Silicon Lottery's samples could reach 5 GHz while running 1.4 volts (with -2 AVX offset), if yours has to run that without an offset to get 4.9, then it's a below average bin.
i didn't say i wanted to hit 5.0ghz. i want it to be at a lower voltage when at 4.9ghz
i didn't ask what LLC did. As i do already know what it does and have tired using every
different setting from 0-8 with different voltages (the bios explains what it does)
and i didn't say i didn't know what binning was. i know that not every single 8600k is going
to be able to hit 5.0ghz or even 4.9ghz, that's what the silicone lottery is.
all i asked was are their "additional settings" that i can change.
that would allow me to lower the voltage while remaining stable.
wasn't being "snarky"
it just doesn't seem like you read that post like at all and just copy pasted a blanket statement.
do you know what the AVX offset does?
5.0ghz with a -2 AVX offset would mean 4.8ghz when running anything that requires it
web browsers like chrome use AVX and if open while gaming, your CPU will be at 4.8ghz
not 5.0ghz. Discord is the same way. alot of programs use AVX.
1.4v with AVX -2 at 5.0ghz compared to 4.9ghz at 1.4v no AVX
is nearly identical and actually better when multitasking to leave AVX offset off
also i haven't even tried 5.0ghz other then to benchmark it with cpuz
(also posted this in the replies)

i don't understand that statement of
"only 87% of Silicon Lottery's samples could reach 5 GHz while running 1.4 volts (with -2 AVX offset), if yours has to run that without an offset to get 4.9, then it's a below average bin"
that doesn't make any sense. AVX lowers clock speed.
the blanket statement of yours didn't really help with anything.
you just explained to me what LLC does and that i may have lost the silicone lottery
because you thought i was aiming for 5.0ghz, witch sure maybe but that's not what
the initial question was.
i just wanted to know what other settings there are other then LLC and voltage
to change, but i guess you didn't read that part or misunderstood what i was asking.
There's also nothing special to this for a CPU overclock, you literally just tweak vCore and the multiplier, and find whichever LLC mode works best. There's no extra settings that's going to make an unstable overclock work.
If you don't know what you're doing with overclocking, then you shouldn't be doing it, and should just sell it at factory settings, because if it's not actually stable, you're selling something that's going to crash, and if the settings are unsafe, then you're selling someone something that's going to degrade and give them issues later. Let them decide if they want to overclock or not.
